When using "Last Week" it will always be from last Monday to Sunday.
When using "This Week" it will always be from the current Monday to
the day selected to pull the report (week ending Sunday).
If you want to select 'your own' day for the week to start, then you need
to use "Between dates". Select week period, for example Tuesday to
the next Monday.
Under Schedule:
the "Date and Time Criteria" will now show "(Daily Interval - Between Dates)".
Under "Schedule Criteria" select:
Weekly from the drop-down for "Frequency".
Tuesday from the drop-down for "Day of Week :".
The same logic will apply for any between date selection range (2 days,
3 weeks, ...).
